trying to locate family members

my name is charles colestock my father is also named charles colestock and is said to live in the duncannon area of pennsylvania. i never get calls from my dad or letters or anything of the like,i am not bitter because of this but i would like to know my family on his side since through blood if not through love we are related.

truth is i am very sick and have been diagnosed with cancer and i would like to at least have some semblance of making amends before i go.
